This might be the most badass viral video we've seen all day, featuring an athlete with a pretty unique specialization: jump-roping. In fact, the woman it features -- named Adrienn Banhegyi -- apparently holds two world records in the sport. Watch her jump rope around Budapest, Hungary, above, and you'll see why.

CORRECTION: An earlier version of this article stated she jumped rope around various locations in Europe. The video was filmed in Hungary. This error has been corrected.
